3.Targets of R&D in China
Basic principles for the energy utilization of biomass
Resource
cultivation and
Clean fuel for rural area :
exploitation
Fuel gas and solid fuel
Promote the
Power development of
generation, liquid fuel-
comprehensive substitution of
utilization

3.Targets of R&D
In the near future(2010):
Biomass power generation: 600MW
Biomass liquid fuel: 2 million ton/yr
3~5% of agriculture and forestry waste can be used
Mid-term target(2020)
Biomass power generation: 3000MW
Biomass liquid fuel: 15 million ton/yr
15~20% of agriculture and forestry waste can be used
Mid-term target(2030)
Biomass power generation: 5000MW
Biomass liquid fuel: 50 million ton/yr
30~40% of agriculture and forestry waste can be used

3.Targets of R&D
Direction of Development
Development of Resources:
Short to mid-term: mainly agriculture and forestry waste;
Give attention to energy crops and energy plants;
Long term: Mainly energy agriculture and energy forestry;
Give attention to new resources, such as energy algae…..
